ROBERT GILMORE CAMPBELL, OF GREENSBORO, NORTH CAROLINA, ASSIGNOR OF ONE-HALF TO OEASAR GONE, OF GREENSBORO, NORTH CAROLINA.

GUIDE FOR WARP-WINDING MACHINES.

CAMPBELL, a citizen of the United States, re-

siding at Greensboro, in the county of Guilford and State of North Carolina, have invented certain new and useful Improvements in Guides for Warpinding Machines; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to warp winding machines, has especial reference to the traverse arm traveling alternately across the machine from one side to the other to guide the warp as it is being wound upon a spool or ball, and the invention consists in certain improvements in guides on the .arms of the traverse which will be fully disclosed in the following specification andclaims.

As heretofore constructed, the arms of the traverse have been provided with conical tubular or trumpet like guides, through which the warp travels, and the warp in traveling through the guides is subject to a deteriorating effect due to friction, which fre quently breaks the fiber of the warp and makes it rough and ragged. It is my purpose to overcome this serious defect, and deliver the warp to the spool or ball in the condition in which it came from the spinning machine.

In the accompanying drawings, which form part of this specification :-Figure 1 represents a side elevation partly in section of the traverse for guiding warp to a winding machine. Fig. 2 an end view of the same, partly in section. Fig. 3 an elevation of one of the guides on an enlarged scale, and showing the arm of the traverse in section. Fig. 4 a top plan view of one of the arms of the traverse detached and Fig. 5 a "top plan of the vertical warp guides.

Reference being had to the drawings and the designating characters thereon, the numeral 1 indicates the shaft of the traverse, provided with opposite spiral grooves 2, 3, respectively, and the shaft is supported at its ends in suitable bearings, not shown, and

is revolved or driven by the means usually employed in such machines.

On the shaft 1 is a traverse or carriage 4, having a vertical arm 5 on opposite sides of which are horizontal guide rolls 6, between which the warp 7 travels, and loops 8 which prevent the warp jumping off the rolls.

8 are guide sheaves supported on arm 9, secured to arm 5, and the sheaves are arranged at a right angle to the rolls 6 and difeet the warp to guides on the ends of the arms 10 of the traverse. The guides consist of vertical rolls 11, in front and adjacent to which is a transverse loop 12 to prevent the warp rising on the rolls, and a transverse bar 13, on which the warp may rest in its passage from the sheaves 8. The upper surface of the bar 13 is rounded to prevent abrasion, tearing or breaking the fiber of the warp as it travels over the bar. The rolls 11 are secured to the arms 10 by bolts 14 and revolve freely thereon, propelled by frictional contact of the warp, without injuring the fiber of the warp, and the arms 10 may be secured to the traverse or carriage by screws 15.

The traverse or carriage 4 is connected to the spirally grooved shaft 1 by a spanner 16, provided with opposite extensions 17 which engage the grooves 2, 3, and the traverse is prevented from turning on the shaft 1, by an arm 18 having a bifurcated end 19 which engages a transverse rod 20 between the sides of the frame of the winding machine, not shown. As the warp 7 proceeds from a spinning machine, the traverse feeds it to the spool on which it is wound, by the guide rolls on the ends of the arms of the traverse without the rupture of its fiber, and thereby preserves the warp in its original condition.

Having thus fully described my invention, what I claim is In a warp winding machine, an oppositely spirally grooved shaft, a fixed rod a laterally movable transverse carriage connected to said shaft, and having an arm extending therefrom and engaging the fixed rod to prevent the carriage turning on the shaft, a vertical arm extending from the carriage having horizontal guide rolls on opposite sides of the arm and loops above the rolls, a horizontal arm secured to said vertical arm below said In testimony whereof I affix my signature guide rolls and lilaving sheiaves thereloln 011 opin presence of two witnesses. osite sic es of t e vertiea arm, ant 1o1'izon gal arms extending laterally from the carriage ROBERT GILMORE CAMPBELL 5 on opposite sides thereof and provided at l/Vitnesses:
